    摘要: A measuring circuit for registering and processing signals received from a transducer having a plurality of transducer elements includes a first signal input, a second signal input and a third signal input. The first signal input is configured to receive a first signal from a first transducer element. The second signal input is configured to receive a first signal from a second transducer element. The third signal input is configured to receive a second signal sum indicative of a sum of a second signal from each of the plurality of transducer elements, each of the second signals being an inverse of a corresponding first signal. A processor is electrically coupled to the three signal inputs and is configured to register each of the first signals individually; register the second sum signal; and generate a differential signal based on the first and second signals.

    摘要: A method and an apparatus for detecting a background noise of a sensor, relating to the technical field of electronics, are provided. The method for detecting a background noise of a sensor includes: receiving a sampling value output by the sensor and judging whether the sampling value falls within a background noise acceptable range; selecting the sampling value as a current background noise sampling value when the sampling value falls within the background noise acceptable range; and calculating a current background noise of the sensor according to a previous background noise and the current background noise sampling value of the sensor. Also provided is an apparatus for detecting a background noise of a sensor.

    摘要: There is provided a measuring device that suppresses flickering of display values displayed on a display and, at the same time, improves response of the measuring device. A measuring device includes a storage that stores information about the measuring device, control circuitry that calculates measurement results, and a display that displays the measurement results calculated by the control circuitry. The control circuitry determines whether or not filtering for suppression of a variation in display values Pn displayed on the display is to be executed and executes the filtering in response to the determination that the filtering is to be executed.

    摘要: Frequency compensation of a vibration sensor digitally in a time domain by using a high-pass filter roll-off slope is presented. The subject matter reduces the noise floor of an analog front end or analog domain portion of a circuit configured to enhance the frequency response of a vibration sensor. The present subject matter eliminates or reduces analog components and adds pieces of signal processing software to digitally enhance the frequency response of a vibration sensor so as to reduce component costs.

    摘要: A multi-pole variable reluctance resolver is balanced wired and driven by 180 degree differential signals. Capacitive passive elements may be serially added to the resolver to minimize magnetic interference and cancel flux between poles of the same polarity and orthogonal poles, as well as minimize the effect of input driving signal distortion. Symmetric networks of resistive and capacitive elements may also be added to the resolver to overcome noise sensitivity associated with balanced wired resolvers.

    摘要: A method for detection of a variable parameter of a vehicle with the aid of a measurement device, by which measured values are evaluated as sensor signals of at least one sensor element which is arranged in the immediate vicinity of an actuating element with an electrical drive, in which no evaluation of the measured values is carried out or performed during an influencing time period between a time of a change in the electrical drive for the actuating element and a time in which this change is essentially still just exerting an influence on the measured values.
